Last December, Jillian Michaels wrote an article for Shape Magazine titled “Why Jillian Michaels Wants You to Stop Kipping in CrossFit.”
Then the anty was upped a little when Shape released a video last Thursday where Michaels had a few other not so nice things to say about CrossFit like how movements “don’t really vary”, “it stops being effective because you’re not challenging the body from various angles of push and pull”, and you should choose an exercise where you’ll “get more mobility.”
We want to maintain a fairly constant back angle through the first pull, although we’ll nearly always see a slight change. It’s important to understand what actually constitutes the starting positionbecause this is a common source of confusion and argument when suggestion the back angle shouldn’t change considerably—the starting position is the posture you’re in the moment the bar begins to separate from the floor. It’s not whatever low-hipped, shoulders-behind-the-bar preparatory position or any given point of a dynamic startyou feel like picking.
The goal is to prevent an excessive and unwanted shift in position. This is a quick shift very quickly after the bar leaves the floor. You’ll recognize it as a sudden rising of the hips while the bar travels relatively little. The hips shooting up dramatically more than the shoulders and bar rise creates a two primary potential problems: It tends to shift balance too far forward, and it tends to force an early second pull, which reduces bar speed and elevation and also disrupts balance.
